Struct aob::Error

pub struct Error<'a> { /* private fields */ }

Describes errors encountered when parsing custom pattern syntax.

Implementations

impl<'a> Error<'a>

pub fn span(&self) -> Range<usize>

The span over which the error was encountered.

let error = DynamicNeedle::from_ida("12 3_ 56").unwrap_err();
assert_eq!(error.span(), 4..5);

pub fn reason(&self) -> &Reason

A human readable reason describing why the error occurred.

let error = DynamicNeedle::from_ida("12 3_ 56").unwrap_err();
assert_eq!(error.reason(), &Reason::InvalidHexdigit('_'));

Trait Implementations

impl<'a> Clone for Error<'a>

fn clone(&self) -> Error<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Error<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Error<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for Error<'_>

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
